Cartridges having interiorly positioned zones of reduced thickness
First Claim
1. A cartridge container containing a substance for preparation of a beverage comprising:
- a body comprising a base, a sidewall and a rim, wherein the sidewall extends from the base to define a container interior, to define a container opening which opposes the base and to define a body shape selected from the group consisting of a frustum and a hemisphere and wherein the sidewall extends from the base to the rim and the rim extends from the sidewall in a direction away from the sidewall;
a cover membrane member affixed to the rim to cover the opening;
a substance for preparation of a beverage contained within the container interior by the body and cover membrane member; and
wherein the base defines both a container base outer solid surface and a container base interior surface and wherein the container base contains a plurality of perforations which define openings in the base which extend for a distance from the container base interior surface through the base towards the container base outer solid surface to provide localized absence of a plurality of portions of the base so that the base has a plurality of zones which comprise a plurality of localized portions of reduced thickness and so that when a fluid pressure for extraction of the substance for preparation of a beverage is applied, the localized portions of reduced thickness tear and open for beverage passage.

Abstract
A cartridge which contains a substance for preparation of a beverage has a cover membrane member which covers an opening of a container body for containing the substance within the container interior. The body has a base and a sidewall which extends from the base to define a container interior, and the sidewall defines the opening at a position opposing the base. The membrane is affixed to a rim which extends from the sidewall in a direction away from the sidewall. An interior container surface of either the base or the cover membrane member contains a plurality of perforations which define openings which provide localized absence of a plurality of portions in the base or cover membrane member to provide a plurality of localized portions of reduced thickness so that when a fluid pressure for extraction of the substance for preparation of a beverage is applied, the localized portions of reduced thickness tear and open for beverage passage.

13. A cartridge container containing a substance for preparation of a beverage comprising:
-
a body comprising a base member, a side-wall and a rim, wherein the sidewall extends from the base member to define a container interior, to define a container opening which opposes the base and to define a body shape selected from the group consisting of a frustum and a hemisphere and wherein the sidewall extends from the base to the rim and the rim extends from the sidewall in a direction away from the sidewall; a cover member affixed to the rim to cover the opening; a substance for preparation of a beverage contained within the container interior by the body and cover membrane; and wherein one of the base member or the cover member defines one container outer surface and one container interior surface and wherein the one member contains a plurality of perforations which define opposing openings in each of the outer and interior surfaces and wherein the openings extend for a distance from each surface through the one member towards a member solid portion positioned between the outer and interior surfaces to provide localized absence of a plurality of portions of the one member and an intermediately positioned member solid portion so that the one member has a plurality of zones which comprise a plurality of localized portions of reduced thickness and so that when a fluid pressure for extraction of the substance for preparation of a beverage is applied, the localized portions of reduced thickness tear and open for beverage passage. - View Dependent Claims (14, 15)
